Abstract
The utility model relates to a RPC leveling board, include RPC bottom plate and a plurality of reinforcing bars of making by the RPC concrete, the RPC bottom plate is rectangle or square, the lower extreme of reinforcing bar is built becomes integrative in the side and with RPC bottom plate rigid connection on the RPC bottom plate. The utility model overcomes the problem that traditional leveling steel sheet resistance to corrosion is weak, the durability is poor has been solved to tradition leveling steel sheet shortcoming. Besides, the utility model discloses a RPC's active powder concrete compressive strength is big, transverse strength is big and toughness is high to the resistance to compression that improves the leveling board greatly reaches performances such as anti book.
Description
Technical field
This utility model relates to a kind of for the leveling board bottom precast bridge, particularly a kind of concrete leveling board.
Background technology
At present, it is usually used in the levelling device bottom precast bridge mostly to be pre-buried or be welded on the steel plate bottom bridge, this levelling device has the drawback that: steel plate corrosion resistance is more weak and durability is poor, leveling steel plate can be made to get rusty when welding or being embedded in the long-time exposure air of leveling steel plate bottom precast beam, so that leveling steel plate obtains comprcssive strength and rupture strength is substantially reduced, and then affect T girder construction serviceability.
Utility model content
The purpose of this utility model is to provide a kind of RPC leveling board, to solve that tradition leveling steel plate, resistance to corrosion be weak, poor durability and comprcssive strength and rupture strength relatively low technical problem.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of RPC leveling board, described RPC leveling board is (ReactivePowderConcrete) RPC leveling board, it is characterized in that: include the RPC base plate being made up of RPC concrete of level and some vertical reinforcing bars, described RPC base plate is rectangle or square, and the lower end of described reinforcing bar is cast in the upper side of RPC base plate and is rigidly connected integral with RPC base plate.
Preferably, described reinforcing bar is along the surrounding position distribution of RPC base plate.
Preferably, described reinforcing bar to the distance at the edge of RPC base plate no less than 30mm.
Preferably, the length of described RPC base plate is 60cm��75cm, wide for 50cm��70cm, thick in for 45��60mm.
Preferably, the diameter of described reinforcing bar is 10mm.
The beneficial effects of the utility model are as follows:
1, this utility model overcomes the shortcoming that traditional leveling steel plate easily gets rusty, and solves that traditional leveling steel plate resistance to corrosion is weak, the problem of poor durability.
2, this utility model adopts that the RPC comprcssive strength of RPC is big, rupture strength is big and toughness is high, thus being greatly improved the performances such as the resistance to compression of leveling board and anti-folding, makes normal use of T girder construction be protected.
3, this utility model can be widely applied in the levelling device bottom precast beam.

Detailed description of the invention
As shown in Figure 1, this RPC leveling board includes the RPC base plate 1 being made up of RPC concrete of level and some vertical reinforcing bars 2, described RPC base plate 1 is rectangle or square, and the lower end of described reinforcing bar 2 is cast in the upper side of RPC base plate 1 and is rigidly connected integral with RPC base plate 1.
In the present embodiment, described reinforcing bar 2 is along the surrounding position distribution of RPC base plate 1.
In the present embodiment, described reinforcing bar 2 arrives the distance h at the edge of RPC base plate 1 no less than 30mm.
In the present embodiment, the long a of described RPC base plate 1 is 60cm��75cm, and wide b is 50cm��70cm, and thick c is for for 45��60mm.
In the present embodiment, the diameter of described reinforcing bar 2 is 10mm.
This practical new manufacture method, its step is as follows:
Step one: set up the mould building RPC leveling board, this mould needs the flatness ensureing RPC leveling board to be not more than 2mm.
Step 2: the reinforcing bar 2 of pre-buried RPC leveling board, and according to position adjustment reinforcing bar 2 position of T beam baseplate reinforcing bar, it is to avoid conflict occurs during installation;
Step 3: build RPC concrete;
Step 4: after RPC concrete final set, form removal also carries out high temperature steam curing; During maintenance, adopt the temperature steam maintenance 72 �� 1h of 80 �� of C, or adopt the temperature steam maintenance 48 �� 1h of 90 �� of C.
Construction method of the present utility model as shown in Figures 2 and 3, its step is as follows:
Step one: RPC leveling board is processed, detect qualified after be transported to job site;
Step 2: according to gradient i% and the RPC leveling board of T beam longitudinal gradient along bridge to length L, calculates leveling block along bridge to discrepancy in elevation H=i% �� L, is mounted to by RPC leveling board in the sand pit (4) of T beam pedestal (5), utilizes sand pit to adjust RPC leveling board two ends discrepancy in elevation H;
Step 3: after RPC leveling board installs, carries out colligation to the reinforcing bar of T web and the reinforcing bar 2 of RPC leveling board;
Step 4: after reinforcing bar binding is complete, installs the template of T beam 3;
Step 5: treat the good after-pouring concrete of model sheetinstallat.
